The main functions and effects of the ASM SMT CPK fixture include the following aspects:
Verify the placement accuracy of the SMT: The CPK fixture can quantitatively measure the offset of the X-axis, Y-axis and Z-axis of the SMT by mounting an ideal component (such as a 140-pin, 0.025" pitch QFP), thereby verifying the placement accuracy of the SMT. Improve the process capability index (CPK value): Through the CPK test, the process capability of the SMT can be quantitatively evaluated to determine whether it meets the production requirements. The larger the CPK value, the better the quality and the higher the pass rate of the process. Ensure production quality and stability: The accuracy of the SMT is one of the key performance indicators in the electronic manufacturing process, which directly affects the accuracy of the SMT processing and the product quality. High-precision SMT can improve the accuracy and stability of the process, thereby improving the CPK value and ensuring the stability and consistency of the production process. Optimize production Production process: By conducting CPK tests regularly, companies can identify key bottlenecks and potential problems in the production process, optimize production processes, improve production efficiency, reduce waste, and thus improve overall production performance.
Supplier evaluation: CPK value is one of the important indicators for evaluating supplier production capacity. Companies can use CPK value to evaluate the production quality control level of potential suppliers, ensure the quality of raw materials and components, and thus ensure the quality of the final product.
Continuous improvement: Through regular CPK analysis, companies can identify deficiencies in the production process, implement improvement measures, improve product quality and production efficiency, and achieve continuous quality improvement.
In summary, ASM placement machine CPK fixtures play an important role in verifying placement machine accuracy, improving process capability index, optimizing production processes, supplier evaluation and continuous improvement, and are key tools to ensure the stability of the electronic manufacturing process and product quality.
